My Sd card is tied up in my 3d printer right now so I tried running your file from pronterface instead. Got the same result as you….charcoal. I aborted the job after a couple of minutes.The movement is much slower and not as smooth as printing from SD directly. I recently upgraded my Marlin too so I may have settings to adjust.
